How does the kubectl proxy command in Kubernetes handle API server authentication?

• A. It bypasses authentication entirely
• B. It automatically handles authentication with the Kubernetes API Server
• C. It requires a pre-configured token
• D. It uses in-cluster authentication only

Answer: (B)

kubectl proxy uses the credentials stored in your kubeconfig and presents them when talking to the API server, so authentication happens automatically. The proxy forwards your requests to the API server with the same authentication method (token, client certificate, etc.) that your current kubeconfig context uses. The API server then validates those credentials on each request. This isn’t a forced in-cluster or token-only setup—any supported method defined in your kubeconfig can be used. In short, the proxy handles authentication automatically with the API server, rather than bypassing it or requiring you to manually supply a token every time.
